Every atom has an atomic number, even Helium. But what is an "Atomic Number"?
The atomic number of a chemical element is the number of protons found in the nucleus of the atom of that element.Ok so I'll take you through some interesting facts and data about Helium (That most people don't know).
Helium Overview
Atomic Symbol
He (Helium)
Description
Light, odorless, colorless, tasteless inert gas. Second most abundant element in the universe. Sixth most abundant in the earth's atmosphere.
State at 20 °C
gas
Sources
Found in natural gas deposits & in the air (5 parts per billion) Constantly lost to space; replenished by radioactive decay (alpha particles).
